MILLVILLE — The man who authorities say caused the death of a local police officer in an early-morning accident in July was allegedly driving drunk when the crash occurred, Cumberland County’s top law-enforcement officer said Friday.

Timothy Seidel is now charged with driving while intoxicated, county Prosecutor Jennifer Webb-McRae announced in a statement.

The 23-year-old Commercial Township man is also now charged with another count of reckless driving, she said.

“No additional comments will be made at this time,” Webb-McRae said in the statement.

Patrol Officer Christopher Reeves, 40, died after a car driven by Seidel crashed into his police cruiser at about 2:15 a.m. July 8 at Broad and Third streets.

Jonathan Seidel, who at the time of the crash was a new city police officer being given a nighttime tour of the municipality by Reeves, suffered a broken arm in the accident. Jonathan Seidel is not related to Timothy Seidel, authorities said.

Police said Timothy Seidel was driving erratically through the city and at a high rate of speed after hitting another police cruiser when the fatal collision occurred.

Reeves was serving as a back-up officer in the incident when Timothy Seidel plowed into his police cruiser.

Seidel is already charged criminally with two counts of aggravated manslaughter and single counts of eluding, vehicular homicide and aggravated assault.

Authorities also charged him with motor vehicle offenses that include two counts each of reckless driving and failure to observe a traffic signal, along with single counts of driving the wrong way on a one-way street, failure to keep right, leaving the scene of an accident and failure to report an accident.

Timothy Seidel pleaded not guilty July 24 in Superior Court in Bridgeton to the criminal charges.

Superior Court Judge Darrell M. Fineman reduced Timothy Seidel’s bail during the proceedings from $400,000 to $100,000. The defendant was remanded to the Cumberland County jail in Bridgeton.
